Toafwwmmayco1wem.. v .Befitlmovvn that'LLnWIe B. ABTHUR, a citizen ofthe United States, residing at Columbine in the .county of `Franklin andState of yidiie, haveinvented new and use- 'ul improvement-.neinvvinternal-iflombustion Engiueago Whieh. the following is aspeciiieav'aion. j y

The vinventien.relatesThe explosion engines, l more particularly to theclass of internal 'combustion engines. The primary object of theinvention is the provision oi an en ine oi this character in 'which arotary valve is arranged for controlling the intake and. exhaust portsduring the operation 'thereo for assuring perfectly silent and uniform.Working of the englne and eliminating reciprocating parte, as Well aspockets in the cylinder to avoid the accu-` A.mulation oi? .'ases.

Anothero jest oi" the invention is the i* provision of a-rotary valve inan internal/ combustion engine which will aord straight 4inlet und@haast-'passages to androm the cylinder thereby' avoi ing sharp anglestherein to retard the iovv of gases, and in y this .manner maximum powerWil-l result as 'well as a more complete scavenging of the cylinder,thereby maintaining high eficieney in the Werking oi" the engine.

Another object of the invention is the provision of a valve for internalcombustion engines in which all cam shafts, idle gears, valve springsand. push rods are eliminated. in, the engine and to assure during theoperation of the letter on the exhaust stroke,

the scavenging ot the cylinder and on the suction. stroke a morecomplete charge, and

also te enteet a greater compression as Well oomhuston directly over thepiston there hy increasing; ythe power and effectiveness of' `theengine.

A. :further object oi the invention l1s the 'provision or a valve forinternal combusengines in which a continuous rotary @movement will heimparted` thereto `directly the crank shaft operated upon by the pistonet the engine so as to assurey correetnessin the openingand closing' ofthe intake and exhaust ports 1n the cylinder. f A further obgect o1' theinvention 1s the `ymovision of a valve for internal combustion engines'which is simple in construction, thoroughly reliable and eilicient inopera tion and inexpensive in manufacture.

With theseand-other ohjeets in view the inventionconsists inthecgnstruetion, combination and arrangement of parte as will behereinafterfmore fully described, illus-l tratedv in the.`accompanyingdrawngs, and pointedout-'in the claims hereunto appended.

In the drawings; Figure 1 is a side elevationof an internal combustionengine con-w and provided. with a bearing for the crank shaft 6, the*same being; formed with a crank 7 whichisiconnectedby means of apistonrod 8 tofa pison. 9, adapted to operate Within the cylinder 10 intheordinary Well-'knownmanner, the said cylinder beingl provided with aWater jacket 11 or other cooling means of the usual type;

Formed in thehead or crown of thel cylinder 10 is a transverselydisposed c v ylindrical tapering valve seat 12 .commun-- eating througha passage 1,3 directly with the cylinder 1,0, Aand this head or Crown isprovided at opposite sides with intake und exhaust openings 14. andlrcspectivelv, the same. opening through the outer Waller" the Waterjacket 11, theint'ake 14 beingin cour munication with a supply conduitleading from a carbureter not shown of the ordi nary Well-known type,while the 'exhaust' port 15 communicates with the lordinary lpine,exhaust not shown. A Fitted Within the valve seat 12 isacorrespondinglyshaped valve plug 16 mounted upon and 'fixed to aturning spindle or axle 17 which has xed at one end thereof a beveledgear --18 meshing With a beveled pinion 19 fixed on lone end of avrotatable valve shaft 20 journaled in suitable bearings 21 projectingfrom4 the cylinder 10, the oppo site end of the valve shaft beinglprovided with a-pinion 21 .meshing Withv a gear22 fixed to one end oftheaerank. shaft 6, the pnions and geene being of a size to permit theValve plug 16 to rotate at one-sixth of the speedv of the crank shaftthereby diminishing the Wear to afminimum onthevalve plug and seattherefor.

The valve plug 16 isl formed with an annular space ooncentricallydisposed with respect to the'axis 01"' movementthereof, the space 23being substantially thelen h of the said plug andbeing designed orestablishing communication between ports 24, 25 and 26 respectivelywhichare formed in the outer wall-of the said plug 16 and are arranged atlequal distances. apart. These ports will register with the'respective-port 13,v intake and exhaust openings 14 and 15,

on the 'Working ofthe valve plug. When the engine lis operating thevalve Aplug 16 is its seat 12 so that` continuouslyrotated in whentraveling the slotv 24 will be brought into registration Withthe intakeport 14 at vthe proper time for thel inlet stroke, at this instant theslot 25 will bein communication with the passage 13 vso as to admit acharge of fiuid. directly into the cylinder 10 and at this instant. theexhaust port 15 is closedso as to avoid the escape `of the chargeadmitted in to the cylinder, land this exhaust" ythe exhaust and inletranged at opposite ends of .the Vvalve and' port reriains closed duringthe entire inlet 91' suction stroke.

.Also the slot. 24s remains 1n communication with the intake port 14during -the entire inlet or suction stroke, and thereafter the saidintake p ort is closed ,at the proper therewith the passage 13 isclosedfor the compression and combustion strokes. At the proper timeforthe'exhauststroke, the 'ein hauet port l5 is uncovered to permit 'thespent gases in the cylinder to escape thereexhaust stroke and suchoperation of the .valve plug1 16: isrepeated'during the continued wor'ng ot the from during .the entire engine;

`It is of course understood that'there is employed in the engine anyordinary Wellknown ignition devlce or system f or Veffecting` theexplosion of thegases at the proper intervals durin' the Working oftheengine.

By` reason o? the snug fit of the valve plug 16 in the seatv A ventedaccumulation of deposits of vcarbon between the valve and mounting thesaid valve plug in the said seat for rotation, it will be revented fromlifting and in' this manner eakage will obyiated.

What is claimed is :--V L 1. An internal combustion engine having aValve chamber provided `with 'an inlet opening, an exhaust opening, anda port communicating with the combustion chamber', a valve rotatablyjournaled transversely in, said valve chamber and having a passageconcentric to its axis and 4openingA through the outer peripheryvthereof at three points with the inlet opening, exhaust opening, andsaid port, the said port during rotation of the valve maintaining suchregistry with one of the o enings in the valve du ring the time ofregistry of the remaining openings successively with openings, disks ar-Working against l the valve chamber' Walls, and means locking said disksagainst' out- Wardl displacement with respect to the Valve. 2. 'A casingformed'with a cylinder hav-- ing" an inlet opening, an exhaust opening,and a combustion chamber passa e, communication with theinlet and.exhaust a valve rotatably mounted in the' and haring ports tosuccessivel" register with said inlet opening, exhaust opening, andcombustion chamber passage, and also provided with a chamber for establishing comm unication between the ports, the said combustion'chamber passgdlfg of a size to maintain registry there'tith of one ofthe ports of the' 'valve during the successive registration of the otherports of said valve 'with the inlet opening and' exhaust opening in thecylinder.
